Subject: configure: error out when building radeonsi without gallium-llvm
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=929f83376aef4ac94ccb9117a5a3df4cc27f525f;p=mesa.git

configure: error out when building radeonsi without gallium-llvm

--enable-gallium-llvm is required by radeonsi. Currently we
check only for LLVM_VERSION_INT which is 0, whenever gallium-llvm
is disabled explicitly.

./configure --with-gallium-drivers=r600,radeonsi --disable-gallium-llvm

v2: Correct typo in error message. Spotted by Tom Stellard
